Detailed Description

Adjacent DW_OP_LLVM_fragment should be merged into one.

E.g. #llvm.di_expression<[ DW_OP_LLVM_fragment(32, 32), DW_OP_LLVM_fragment(32, 64) ]> => #llvm.di_expression<[DW_OP_LLVM_fragment(64, 32)]>

Member Function Documentation

MergeFragments::OpIterT MergeFragments::match ( OpIterRange ) const

overridevirtual

Checks whether a particular prefix of operators matches this pattern.

The provided argument is guaranteed non-empty. Return the iterator after the last matched element.

SmallVector< MergeFragments::OperatorT > MergeFragments::replace ( OpIterRange ) const

overridevirtual

Replace the operators with a new list of operators.

The provided argument is guaranteed to be the same length as returned by the match function.
